2 Qlaims. (Cl. 16-128) This invention relates to door hinges of the type in which the pivot point of the hinge is spaced from the meeting edges of the door and frame whereby the door, in the open position, is spaced beyond the edge of the frame providing a complete opening to permit free passage of furniture and the like and also, when used for garage doors, to protect doors from motor vehicle bumpers, fenders and the like.

The purpose of this invention is to provide an offset door hinge that permits a door to open to a full open position without occupying a portion of the opening through a doors frame.

With the conventional type of butt or strap hinge that is used for doors of a residence, garage, barn or the like and that is also used for casement windows the swinging element, such as the door or sash swings inwardly into the path of the opening reducing the width of the opening so that in numerous instances it is necessary to remove a door to move a desk or other piece of furniture through the door. This is objectionable because it is necessary to remove and replace screws and the screws soon become loose. With this thought in mind this invention contemplates a hingle having an offset pivot point whereby the door swings from a point spaced from the meeting edges of the door and frame so that in the open position the inner surface of the door is spaced from the edge of the frame.

The object of this invention is, therefore, to provide means for forming a door hinge whereby a door swings about a pivot point spaced outwardly from the edge of a door frame in which the door is positioned.

Another object of the invention is to provide an improved door hinge wherein the pivot point is spaced from the meeting edges of the door and frame in which the hinge elements include overlapping flanges so that, in the closed position, the door is supported from the edge of the frame to the pivot point of the hinge.

A further object of the invention is to provide a hinge for doors and the like in which the pivot point is spaced from the meeting edges of the door and a frame in which the door is positioned in which the hinge is of a simple and economical construction.

With these and other objects and advantages in view the invention embodies a mounting base, channel-shape in cross section and having a vertically disposed pin mounted in one end, a door section, also channel-shape in cross section having flanges nested over flanges of the base and pivotally mounted in the base and tabs extended from the base and door sections and recessed in the meeting edges of the door and frame.

Other features and advantages of the invention will appear from the following description taken in connection with the drawing, wherein:

Figure 3 is a cross section through the hinge taken on line 3-3 of Fig. 2.

Figure 4 is a cross section through the hinge taken on line 4-4 of Fig. 2.

Figure 5 is a sectional plan through the base of the hinge showing a portion of the door section of the hinge extended therefrom, said section of the door portion of the hinge being broken away and part of the door frame also being broken away.

Referring now to the drawing wherein like reference characters denote corresponding parts the improved hinge of this invention includes a base 10 having an upper flange 11, a lower flange 12, and a tab 13, and a cover or door section having a web 14 with a flange 15 extended from the upper edge and positioned to slide over the flange 11 of the base and a flange 16 extended from the lower edge and positioned to slide under the flange 12 of the base and, as illustrated in Fig. 1, the cover 14 is provided with triangular-shaped flanges 17 and 18 extended from upper and lower edges thereof, respectively and tabs 19 and 20 that extend from the edges of the flanges l7 and 18 and that are recessed in the edge of a door carried by the hinge, the recesses being indicated by the numerals 21 and 22.

The base 10 is provided with a rolled edge 23 and a pivot pin 24, extended through a hub formed with the rolled edge 23 is journaled in the hub with bearings 25, as shown in Fig. 5.

The base is positioned against the face of a door frame, as indicated by the numeral 26 with the tab 13 positioned in a recess 27 in which the tab is held with a screw 28, and with the screw 28 in position screws 29 are placed through the base and screwed into the frame 26, as shown in Fig. 1. By this means the base is rigidly secured to the door frame and the upper and lower ends of the pin 24 are secured in the flanges 15 and 16 of the cover 14-. The pin 24 is provided with a head 30 and the lower end is peened as indicated by the numeral 31.

The cover 14 is secured to the door, which is indicated by the numeral 32 with screws 33 extended through the flanges 17 and 1%, screws 34 extended through the beveled sections 35 at the extended end of the cover and screws 36 that are positioned in the tubs 19 and 29, respectively, extended from the edge or ends of the flanges 17 and 18.

With the parts assembled in this manner and with a door hung in a door frame with hinges of this type the door swings away from the door opening through the frame as illustrated in Fig. 2, whereby the inner surface of the door is spaced from and protected by the inner edge of the frame in which the door opening is provided. By this means the width of the door opening is increased so that a 28-inch door may be used where a 30-inch door has been hereinbefore required and with the inner surface of the door positioned behind the edge of the frame the door is protected from motor vehicle bumpers, furniture and the like.

It will be understood that modifications, within the scope of the appended claims, may be made in the design and arrangement of the parts without departing from the spirit of the invention.

What is claimed is:

1. A hinge comprising a base, a cover positioned over the base, the length of the cover being greater than that of the base, and means pivotally connecting one end of the cover to one end of the base with the opposite end of the cover extended beyond the opposite end of the base, said cover and base being adapted to be positioned on a door and door frame, respectively, with the base mounted on the frame and the cover mounted on the door and, with the pivotal connection between the cover and base extended from meeting edges of the door and frame, the edge of the base opposite to that on which the pivotal mounting is positioned having a right angularly positioned tab adapted to be recessed in the frame and the corresponding portion of the cover also having triangulariy shaped flanges at the side edges thereof and a right angularly positioned tab on the end of each triangularly shaped flange adapted-to be recessed in the door.

2. In a hinge for a door, the combination which cornprises a base, channel-shaped in cross section having flanges extended from upper and lower edges thereof, and having a vertically disposed hub on one end and a tab extended at a right angle from the opposite end, a cover also channel-shaped in cross section having flanges extended from upper and lower edges thereof positioned over the base with the flanges of the cover slid-ably mounted on the flanges of the base, and a pin extended through the hub of the base for pivotally mounting the cover on the base, said cover having a section extended beyond the end of the base opposite to that on which the hub is positioned and said extended section of the cover having triangularly shaped flanges on the edges with tabs extended at right angles from ends of the flanges, the outer surfaces of the tabs of the cover being positioned in a plane corresponding with a plane through the outer surface of the tab of the base.
